Recently, Asia's
largest manufacturer of sun power inverter Inc. announced that its new inverter
SG30KTL in the German market gained another successful application . It is
reported that the announced projects are located in Berlin, Germany,
near the famous Athos Solar PV companies , with total installed capacity of
8.3MW.

Inverter power regulator , also known under
the inverter PV system in use can be divided into independent mode power
supplies and grid with two kinds . According to the waveform modulation mode
can be divided into square wave inverter , step wave inverter , sine waveinverter and modular three-phase inverter . For grid systems for inverter
transformer can be divided according to whether the inverter transformer and
transformerless inverters . There are many types of the inverter , so the
selected machine type and size of the need of special attention. Especially in
the solar power system, inverter efficiency is to determine the size of solar
capacity and an important factor in battery capacity .

In China's " Eleventh Five-Year
" period, such as photovoltaic inverters and other equipment in various
stages of R & D and innovation , less vulnerable to policy concerns .
"Twelve Five" period, the PV market trend is towards the development
of the whole industry chain , crystalline silicon , a component other than the
equipment will be subject to further market and policy concerns , the NDRC will
be included in the Catalogue inverter encouraged , it is that a trend
reflected.

Currently international photovoltaic
inverter industry leader in the German Asma (SMA) companies, technology in the
industry vertices. Compare the strength of the domestic grid inverter
companies: Hefei Sunlight Power Supply , three crystal new energy, national
grid XJ Group Corporation , CIMIC , Samil Power , Beijing Corona , Esso new
energy, Xi'an love , etc. ; while off-grid inverter technology is relatively
mature, has a number of technologically leading companies .
